Description
~~~~~~~~~~~

This block is a sawtooth wave generator. The output of the block is
described by the equation:



At first event on its activation input, the output increases linearly
from 0 with a unitary rate. When the following event occurs, the
output goes to 0 and begin again to increase until the next event and
so on.

The resulting amplitude of the output is equal to the period of event
signal. If you want more control on the amplitude or a negative rate,
use the `Sigbuilder`_ or `Curve_f`_ blocks.
